In the past, Greek theatre was much different than the theatre's in our present. They didn't have half the things we have. For one the greek theatre's had no microphones. So in order to project the voice of an actor they usually used chorus work. There are however a few key words that you should note about ancient greek theatre.
• The first one here is "Acropolis" this is a city which tents to lie around a hill. Usually an acropolis had only two theaters in disposal and one of the common theaters was a bit smaller than the other. This was a theatre of Dionysos.
• The seats of honor were reserved for the high priest of Dionysos. These were usually placed at the very front seats, which where around 50 to 67 sets of seats in that row. These seats were usually called the seats of honor.
• A "scenery" is a place were actors usually changed costumes, and masks. It was shaped like a wooden box with only one entrance. The inventor of the scenery was a man named Sophokles. He created the scenery mainly by painting the outside of a scene building.
• A "Mekhane" is a sort of crane that helps actors show a flying god/creatures into the play. It was used to lift off the actor above ground to make a special effect to the scene.
• An "Orchestra" was an area where the actors danced and sung. It also gave representation to the god of wine which had created greek theatre in the first place.
• Now the only actors which performed on stage were men, who played parts of female and male. They showed the characters by wearing different costumes and masks.
• After every play the judges gave prizes to the best writer of plays. It was indeed great honor and privilege to win a prize. Most of the famous scripts pass on to around two and a half thousand years so we can still read them today.
